I can boot a parisc image to CLI using ToT qemu, ToT kernel built with
	make ARCH=parisc CROSS_COMPILE=hppa-linux-" defconfig
	make ARCH=parisc CROSS_COMPILE=hppa-linux-"

qemu command line:

qemu-system-hppa -nographic -monitor none -kernel vmlinux \
	--append "console=/dev/ttyS0 root=/dev/sda" \
	-drive file=rootfs.ext2,format=raw,if=scsi

I built the root file system using a modified buildroot based on 2018.02-rc2
with hppa support added.
